IMPROVEMENT IN STARCHlNG-MACHINES.

Specification forming part of Letters Patent No. 135,171, dated January21, 1873.

To all whom it may concern:

Be it known that I, LEOPOLD STEENBER- GER, of Philadelphia,Pennsylvania, have invented an Improved Starching-Machine, of which thefollowing is a specification:

The object of my invention is a machine for rapidly and thoroughlyrubbing starch into and through the fabric of shirts and other articlesof wearing apparel. I accomplish this object in the manner best observedin the perspective view, Figure 1, of the accompanying drawing, bycombining an oscillating or vibrating rubber, A, operated rapidly from apower-driven crank-shaft, B, with a rubbingbed, D, rendered verticallyadjustable toward and from the rubber by means of a treadle, E, andconnecting-rod a, the said treadle also controlling the belt-shifter b,through the medium of the devices hereafter described, so that when thebed is raised by the said treadle, and the shirt or other articlebrought in contact with the rubber, the latter shall be instantly set inmotion, and be similarly stopped when the bed is lowered.

The rubber A is secured to a vibrating arm", 0, pivoted at d to a post,0, projecting upward from the frame of the machine, the said'arm beingconnected by a rod, f, to a short crank, g, on the shaft B, which hasfast and loose pulleys at one end, into either of which the driving-beltcan be passed by the shifter 12, the latter, as best observed in Fig. 5,being connected to a slotted arm, h, hung to a bell-crank lever, I,which is, in turn, connected by a rod, j, to the connecting-rod a,between the operating-treadle and the rubbing-bed D. The latter isadapted to vertical guides on the frame of the machine, and is free fromcontact with the rubber A, except when raised and held against the sameby pressing upon the treadle E; and the said bed has a ledge or flange,k, at the back, as shown in the perspective view, Fig. 2, and aconcavity, 1, within which the rounded face m of the rubber works.

In using the machine the operator places a starched shirt or otherarticle upon the rubbing-bed immediately beneath the rubber A, and bypressing upon the treadle simultaneously starts the rubber and raisesthe bed so as to press the shirt against the same. The rubber vibratesvery rapidly, and by the pressure of its rounded lower surface upon theshirt thoroughly rubs the starch into and through the same, the positionof the shirt being shifted as it is rubbed until every por tion isreached.

The rounded surface of the rubber fits snugly into the concavity of therubbing-bed, which retains the starch, and thus much facil itates theoperation.

It will be observed, in reference to the perspective view, Fig. 3, thatthe rubber has a recess, 19, at the back. This is for the passage of thebuttons in starching shirts, the latter being turned inside out and thenfolded longitudinally at the center of the bosom, so that the buttonsmay lie against the rear flange 7c of the rubbing-bed without beingstruck by the rubber. In order that the space between the buttons,however, may be properly starched, a yielding stud, s, Fig. 4, isadapted to the recess p of the rubber, and is so arranged that it willride over the buttons and rub the spaces between the same.

I claim as my invention- 7 1. In a starching-machine, the combination,substantially as described, of an oscillating rubber, A, with arubbing-bed, D, rendered adjustable toward and from the said rubber.

2. The oscillating rubber A, with its rounded face m and recess 19, incombination with the concavity I) of the rubbing-bed.

3. The combination, substantially as described, of the yielding stud swith the recessed rubber A and rubbing-bed.

4. In a starching-machine, the combination, substantially as .described,of the operatingtreadle E and connecting-rod a of the rubbing-bed withthe rod j, bell-crank lever c, slotted arm h, and belt-shifter b, or anyequivalent devices, whereby the oscillating rubber may be set in motionsimultaneously with the raising of the bed by the treadle, and stoppedsimultaneously with the lowering of the said bed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

LEOPOLD STERNBERGER.
